DYS Quanum 40A ESC with 5V/3A BEC

The DYS Quanum 40A is a programmable brushless multicopter ESC with an integrated 5V/3A BEC, giving drone builders steady 5V power for the flight controller and other electronics straight from the ESC without a separate regulator.

Key features

• Synchronous-rectification hardware design lowers output resistance for better power stability and less strain on the battery under load.
• Supports high motor speeds: up to 210,000 RPM on 2-pole motors, 70,000 RPM on 6-pole motors and 35,000 RPM on 12-pole motors.
• Startup safety lockout keeps the motor from spinning up on power-on regardless of throttle stick position, reducing the risk of an accidental start.
• Separate voltage regulation for the microprocessor improves noise immunity in electrically busy multirotor builds.
• Integrated BEC removes the need for a standalone 5V regulator on simpler builds.

Specifications

• ESC current: 40 A
• BEC output: 5 V / 3 A
• ESC type: Programmable brushless multicopter ESC
• Firmware: SimonK (multicopter build), with a crystal-oscillator-clocked MCU

Confirm the motor pole count, wiring and flight-controller BEC settings before powering the build, and avoid drawing BEC power from more than one ESC at once.
